Bug#1105139: libjemalloc2: Don't assume altivec on powerpc

Package: libjemalloc2
Version: 5.3.0-3
Severity: important
X-Debbugs-Cc: [email protected], [email protected]
User: [email protected]
Usertags: powerpc

This package's rules file explicitly enables Altivec on powerpc, but
many powerpc machines use G3 or earlier processors that don't support Altivec.

This results in a SIGILL when packages linking against jemalloc are run on those
machines. Eg: on an iBook G3 running tmux, I get a SIGILL on a 'vxor' instruction.

Debian policy has traditionally been to support baseline CPUs when it's at all
possible, so this package should disable Altivec on 32-bit powerpc.
